CONCRETE MOLD.

Application filed September 29, 1923. Serial No. 365.655.

To all whom t may concern.' I Be it known that I, ADAM Trsxinwioz, a citizen of the United States of America, residing at Rothschild, in the county of Mara thon and State of Wisconsin, have invented certain new and useful Improvements in Concrete Molds, of which the following is a specification. Y p

This invention relates to certain new and useful improvements in concrete molds of the type employed in the building of floors, walls or the like wherein reinforcing I-beams are embedded in the concrete with the mold formed of separable and expansible sections. The primary object of the invention is to provide a concrete mold for floors, walls or the like wherein separable and expansible' mold sections are constructed in a manner for rigidly supporting reinforcing I-beams in positions, either for completely embedding the I-beam in the molded concrete or embedding the I-beam ywith one flange face exposed.

f A further object of the invention is to provide afconcrete mold of the above type Whereinthe, mold sections are constructed for interlocking engagement with supportingybars thatfhold concrete forms or arched lmembers properly positioned during the molding operation. 1-

With the above and other objects in view as the nature of the invention is better understood, ,the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shownjin the accompanying drawing and claimed.

In the drawing, wherein like reference characters designate 'corresponding parts throughout the several views,

lThe concrete mold disclosed in this application being intended for use in connection with the formation of flattened ,or plain bodies or surfaces, such as walls, floors or the like and for` supporting I-beams. as rein? forcing elements and arch supports for the concrete during the molding operation,`thc

-mold embodies similarly formed cooperating clamping mold members, each including a body portion l cutaway at one corner edge thereof as at 2 and carrying an upwardly directed shoulder 3 at the longitudinal edge ofthe cutaway portion, as clearly shown in Fig. 6. The bodyportion l is vformed with a transversely extending elongated slot portions thereofare assembled as illustrated in Fig. 2, the slottedopenings 4 register and have a clamping bolt 5 passing therethrough for holding the mold sections in adjusted positions. The body portion lat the end 4 so that when the two mold sections or body thereof opposite the slotted opening l carries an elongated extension 6 having spaced cutaway portions of unequal depth upon one side thereof as at 7 and 8 to form `a laterally extending arm 9, while the extreme outer end of the extension member 6 carriesan. angularly directed arm l0 projecting in a Ydirection opposite the arm 9,- this construction being clearly shown in Figs. 2V and 6; The body portion lis provided-with an upwardly directed transversely extending rib 11 while f the body portion as ting` each other and alined with the ribs 11 The clamping` sections ot the mold are arranged in spaced relations and in spaced rows with a longitudinally extending board let supported upon the shoulders 3 and ribs 11, a clamping block 1i? illustrated in detail in 7 being p /`tioned adjacent each side edge of the board la and embodying a base tlange 16 resting upon the board as shown in Fig. l'with an upper clamping engaging the adjacent edge ot the base 'th 18 of a reinforcing l-beam 19 that is ported on the base iianges 16 ot cooLLx-.rating clamping blocks providing` a space between the base flange 18 ot the -beam anu the upper Ytace ot the board Arch 'forms are associated with the mold sections and board 141, each including an upper wall 20 and deiloending side walls 21, the lower ends of which rest upon opposite edges ot the board 11i, the arch being turther supported by an upper horizontal bar 22 engaging the lower tace ot the upper wall 20 of the arch `form, while end bars 23 are interposed between the opposite ends ot the upper horizontal bar 22 and the outer ends of the mold sections. As shown more clearly in Figs. 6 and 8` the supporting bars 23 are cutaway at their lower ends for interlocking engagement with the outer ends oit the mold clamping sections, the same having a transverse slotted opening 24k communicat ing with the slotted opening 25 extending at right angles thereto to term depending feet 26, 27 and 28, the toot 26 being positioned laterallyof the end extension G olf the mold section with the outer edge thereof engaging the inner tace out the arm 10, the foot 28 being positioned between the shoulder 11 and arm 9, while the toot 27 is positioned outwardly ot the arm 9 and adjacent the cutaway poition 8. Clamping screws 29 threaded through the openings 13 in the mold clamping sections treely pass through openings 11i" in the board 'la for reception in the threaded openings 30 in the base anges 16 oit the clamping blocks 15, the screws 29 anchoring the mold clamping sections in position together with the board V1l. and clamping blocks 15, Concrete 81 or similar material is filled in the mold as shown in Figs. 1 and l, and as illustrated in the former ligure, completely embeds the l-beam 19 with the clamping blocks 15 associated therewith. After the concrete has become set, the clamping screws 29 are removed and theclamping blocks remain united with the concrete and reinforcing -beam 19 that is completely embedded in the concrete and the mold sections and arch Yforms with their supporting bars are removed from the molded concrete.

When it is desired to embed the .l-beam in the concrete with the lower tace of the base flange thereof exposed, the `cooperating side oortions 21a ot the arch forms 2O being` cut-avay at their lower ends as at 21h to straddle the clamping lugs 12 for support directly upon the mold sections. lt is also intended to construct the mold sections as illustrated in Fig. 5 for use in supporting relatively larger l-beams, the body portions o1" the clamping sections being provided with longer slotted openings la in which pair oi" clamping bolts .3a are mounted while the upwardly directed shoulders 3a are olZ greater length to provide an extended support for the base flange ot an l-beam.

'F rom the above detail description of the invention, it is believed that the construction and operation thereof will at once be apparent. .and while there herein shown and described the preferred embodiments ot the present invention, it is nevertheless to be understood that minor changes may be made therein withoutdeparting from the spirit and scope oi'l the invention as claimed.

What is claimed as new is l. ln a concrete mold, a plurality ot clamping members arranged in spaced relation and in spaced' rows, each clamping member including separable sections, means cooperating with corresponding sides of the sections adapted for engaging opposite side edges oit the i'ianges of reinforcing I-beams, a board adapted to be supported on the op* posite corresponding sides of themold sections, and clamping screws threaded through the mold sections, freely passing through the board and threaded into the clamping blocks.

2. In a concrete mold, a plurality ot clamping members arranged in spaced relation and in spaced rows, each clamping member including separable sections, means cooperating with corresponding sides ot the sections adapted tor engaging opposite side edges ot the flanges oit' reinforcing beams, a board adapted to be supported on the opposite corresponding sides of the mold sections, clamping screws threaded through. the mold sections, freely passing through the board and threaded into the clamping blocks, and arch forms supported at their edges ron the board.
